How to rewrite nim programming langauge to be pythonic as possible?

mhh I forgot to reply and resurrected my forum account just now. By the way, 
you're very wrong, in a language like Python not only are exceptions for 
control flow idiomatic, but they're not even that slower overall (especially 
when compared to not handling them or using if statements)
